My truck doesn't overheat when I drive freeway speeds, but when I wheel . . I have to take the hood off to wheel. I am wonderin what I can do to check my cooling system to see what is failing. All my belts are tight, so I think the pulley to the water pump is turning fine. Dunno . . .

Go down to the local pressure washer carwash joint and hit your radiator from the front and from the fan-side as thoroughly as possible. You can pretty much poke that nozzle against the radiator without hurting the vanes. Mine boiled over when crawling before I did this. Took more than 5 minutes for all of the water to come out without being brown, and now it runs about 2/3 of the way to the red, instead of in it.

Do this before anything else because it's worked for me and hey, it the cheapest solution you're going to find, so why not try it first?</font>

do you have a body lift?


i had the same problem and thats becouse the i never lowered the radiator and the fill point was lower than the radiator.

this was caused by the body lift so i lowered the radiator and it is all sweet now.

I played that game with my truck this past summer. I replaced the radiator hoses belts and thermostat and still had problems with low speed overheating. It turned out to be the fan clutch. You could hold the fan while the engine ran, I replaced it with a 16" electric fan from advance auto and have had no problems with it. It was a costly adventure but the truck honestly needed the radiator and hoses because they were both pretty crappy. Good luck.
